"Toto, I've a feeling we're not in ... anymore" (The Wizard of Oz) (6)
I believe the answer is:
kansas
(Other definitions for kansas that I've seen before include "American state, capital Topeka" , "Midwestern US state" , "Dorothy and Toto lived here on a farm" , "seen about in region round Topeka" , "US state, capital Topeka" .)
